macOS 27 Golden Gate is here, and like every year, it's time to dig around and find out how Archicad runs on it. So far, the only thing I've found is an post from August that says pretty much nothing about Archicad 29. I know the universal answer is "don't upgrade." Still, I...

If an IFC model being hotlinked into Archicad doesn't contain layers in IfcPresentationLayerAssignment, all elements are stored in a single layer by default. This complicates further work when you want to display only terminal HVAC units, or hide distribution runs altogether...

If you caught the news a few days ago about the addition of the still-experimental computer use feature to Claude Cowork and Code*, and wondered whether it could work with Archicad on its own — the answer is yes. My experiment is here: https://youtu.be/d4GDtEw_qC4 The prompt...

Hello GS, I'm currently exploring the implementation of IFC 4.3 in Archicad 29 and I've found that in terms of the IFC schema extent and class naming, the state seems to me as completely identical to IFC4. Are there any plans for further adaptation (or rather extension) acco...

Could you please finally make Archicad save work continuously without the possibility of losing hours of work by accidentally clicking 'Don't save' when closing Archicad? Just like it's common in 2025 with most other applications (at least on Mac)? Thank you. (Lost just 3 ho...

I worked up the courage too and installed macOS 27. So far, the only problem I've run into is with an older library of my own (an LCF created roughly in Archicad 25–27): Archicad 29 reports it as incompatible, even though it worked fine on the previous macOS. However, I also...

Hi Zoltan,Honestly, I've spent the last few weeks thoroughly examining IFC 4.3, and in terms of modifications and new features in the new schema, exactly zero has been implemented in Archicad. Archicad can save a model in this schema version, but in reality it provides no be...

I'm in the same situation, Archicad on Mac and the outputs don't match colors. It looks like a minor issue, but realistically those outputs look really bad (especially after printing everything is too dark). I've tried everything possible, and the only thing that worked and ...

That also entertained me quite a bit. Especially when GS promotes the global library with the arrival of Archicad 28 – and on the other hand limits the plan to one language version (I know they're not directly related, but communication-wise it's not very fortunate).

The Solo plan isn’t available in our market at all. And with only about a 10% price difference between Collaborate and Studio, I think most rational users will opt for the more expensive plan. (Honestly, I believe GS initially intended to "motivate" users toward this step by...
